SOURCE: car leaking coolant

First of all ensure that your car is leaking coolant fluid, and what is dripping is not just water condensation from the air conditioner.
If you have a coolant liquid leak, it can be from one of the ducts leading to radiator , from water pump or radiator itself. Check liquid levels, and if you have a leak have the car inspected by a qualified mechanic.
A broken water pump, for example, can cause your motor to blow in few miles.

SOURCE: No visible coolant leak on a 98 Buick park ave , looseing coolant

A common problem on the 4.9 , 3.8 , and 3.4
is intake manifold gasket failure GM has not recalled
this problem , look for oil and anti freeze marks on side of the block . Or the oil dipstick for milky
residue . Sometimes an engine light will be triggered also . You can also have the emmissions test to detect High levels of Hydro Carbons . From the coolant cap location this will tell you if its a internal problem like head gasket
or intake .

SOURCE: leaking coolant, oil, poorly running, won't shift into gears now

First determine where coolant loss comes from. I would not continue driving, till that step is isolated, or further damage will be done

u have a leak in the heater core the oily smell and mist is anti freeze sounds like a small leak because usually u would have a wet floor if it was large -two choices check and repair as necessary the core or can use an additive with a stop leak they usually work well on small leaks

SOURCE: car leaks coolant but does not overheat leaks alot

find out where the coolant is leaking from, a minor leak could become a major leak at the wrong time. check your hoses. how much coolant are you having to replace. If you don't see where the water is leaking from try warming the care up or looking for the leak after you car has been driven. Be very careful hot water can cause serious burns.

How come I have a bad smell when I start my 05 Pontiac Montana SV6 and heat won't kick in??


Any chance you have loose "fan" belts, they may be slipping and it smells like burning rubber? Or could be a bad coolant leak if the smell is like antifreeze, so not enough coolant to get to the heater coil. Have you checked your coolant level recently?
And perhaps all fluid levels need to be checked. Have you had it serviced by a competent well recommended Mechanic at the recommended service times?

Change all the radiator hoses. If you still smell coolant it could be coming from your heater core. If that goes out the floor of the vehicle will be wet and the windows will steam up.

You have a rich fuel mixture that ruined the exhaust converter

Google the PO430 code

The smell may be a coolant leak on the exhaust

Get the coolant pressure tested,its definitely leaking coolant.You will need to get the coolant running line.
Pressure test will help you to know from where exactly coolant/refrigerant is getting leaked.===========For complete step by step troubleshooting i suggest you to go through the help links mentioned below :----Click the link below :-----

97 seville overheats slowly and loses quite a bit of anti-freeze but not smoking,or mixing in the oil and not steaming uot of the exhast.


My first guess would be the cooling system has some air in it from the radiator job, or the thermostat may be sticking.
You say it is loosing coolant, so you are putting coolant in every day or week ? Is it loosing it on the ground when it overheats ?
If you are adding coolant but not seeing it boil over, it could be burning it and you would not see smoke from the exhaust.

My 2001 lincoln ls slowly moves to overheating when it is running it doesnt jump but it overheats need to know why


These cars have a hydraulic cooling fan, and they can go bad.
The usual potential cooling problems apply, and the crazy hydralic drive just makes it more complicated. An electric fan is good or bad, but a hydralic fan can slowly loose the ability to spin fast enought to get the job done

Overheating


I would recommend that you bleed all air out of the cooling system. The bleeder valve is located on top of the engine. Once engine starts to overheat or when you can hear bubbling back into the overflow bottle, turn car off and open bleeder valve. If you see bubbling you have air in your system. Bleed the system a couple of times and see if this helps.A heat sensor sending unit which controls activation of the electric fan could also have failed.But if the heat sensor is properly working then check the radiator cap is it properly fitted or got loose.If its loose it will release the pressure and car will overheat.But if the radiator cap is properly closed.Then its time to check the HEAD GASKET.As you have replaced the head gasket still get it checked is it overheating very quickly or is the head gasket placed properly also check the coolant level in the car. Thanks. you can rate this solution and show your appreciation.

05 cts v6 drove car,when i stopped an let it sit for a few min.when i tried to start again the key turned on but would not start and key would not come out. the only way it will come out is by unhooking...


I dont remember the name for it.VATS I think it's called,it a security item inside your steering wheel the little wire breaks and the system looses it's sense to know what's going on.The car thinks you are in drive mode.

Changed entire cooling system and still overheats


The overheat sounds like an air pocket in the cooling system there are two bleeder screws located on top of thermostate hosing and 1 on the metal pipe just above the water pump I believe they are 7mm. with the radiator cap off and the car running slowly open 1 bleeder at a time just crack it loose until you get a steady stream of coolant make sure to keep the level in the radiator up. be carefull coolant may be hot! when you take the oil cap off you are creating a big vacuum leak thru the PCV (positive crankcase ventalation) system this is normal for this car to surge or die.
